PM Axis-Matched Low Ratio Tap
波長 ： 900 ～ 1600 nm
For low power monitoring in the wavelength range of 900～1600 nm, while maintaining polarization.
G&H’s proprietary PM manufacturing technology provides tap ratios as low as 0.01% with low loss and high signal path polarization extinction ratio. Fused PM Axis-Matched low ratio taps exhibit outstanding tap ratio stability even when system polarization extinction ratio levels are low or fluctuating, and the all-fiber construction and excellent loss characteristics provide exceptional reliability at high power.
This LRT operates within a wide temperature range, with a temperature-dependent loss of typically <0.002 dB/°C for the tap path. These high-performance LRTs are available at a range of wavelengths with different fiber options. Fused PM LRTs can therefore be readily specified in a wide variety of applications, enabling rapid design cycles and new project builds.
